## 12. Future Enhancements

1. **Directory Leases**: Extend lease support for directories
2. **Lease Key Persistence**: Save lease keys for reconnection
3. **Parent-Child Relationships**: Implement hierarchical leases
4. **Lease Sharing**: Support lease sharing across handles

#### 1.2 Implementation Tasks
- [ ] Define lease state constants (SMB2_LEASE_READ, SMB2_LEASE_HANDLE, SMB2_LEASE_WRITE)
- [ ] Implement lease key generation and management
- [ ] Add lease context to Create request/response
- [ ] Implement lease break notification handling

- **MS-SMB2 Section 2.2.36**: SMB2 Change Notify Response
- **MS-SMB2 Section 3.3.5.9.11**: Directory Leasing and Caching

## 3. Directory Lease Types

### 3.1 Directory-Specific Lease States
```java
public class DirectoryLeaseState extends Smb2LeaseState {
    // Standard lease states apply, plus directory-specific semantics:
    
    // READ_CACHING for directories means:
    // - Can cache directory enumeration results

        setRequestedOplockLevel(SMB2_OPLOCK_LEVEL_LEASE);
    }

    /**
     * Add a lease V2 context to this request
     * @param leaseKey the lease key
     * @param requestedState the requested lease state
     * @param parentLeaseKey the parent lease key (can be null)
     * @param epoch the lease epoch
     */

        entry.markComplete();

        // Break lease with loss of read cache
        int newState = Smb2LeaseState.SMB2_LEASE_HANDLE_CACHING; // Lost read cache
        directoryLeaseManager.handleDirectoryLeaseBreak(leaseKey, newState);

        // Cache should be invalidated
        assertFalse(entry.isComplete());

        // Verify base lease manager was called
